As a book and video game enthusiast, my unpopular opinion is that the average video game is a much better entertainment value than the average book.
I've played a lot of games and read a lot of books.
When measuring dollars for hours, I think video games win.
On the one hand, I've put massive numbers of hours into titles like Zelda, Metroid, Harvest Moon, and Pokemon.
On the other hand, I've only gotten two or three read-throughs out of even some of my very favorite books.
And then the video game classics really put up some big numbers: after decades, I'm still enjoying PacMan, Frogger, and Galaga and their kin.
And then there's the elephant in the room: Tetris.
If I had to pick - on a desert island - between an e-reader with every book ever printed, or one copy of Tetris on a Gameboy...it would be an agonizing choice.
